CCS - MV Bluefin 2018 V02 Multibeam Echosounder

Full description

roject Overview: A range of solutions will be required to reach globally agreed emissions reductions targets for carbon dioxide (CO2). Carbon capture and storage (CCS) is part of the suite of technologies that will contribute to lowering atmospheric emissions of CO2 from Australia's energy system. There are a wide variety of technologies at various stages of technical and commercial readiness, with more development underway for cost effective CO2 capture and storage. Our research will provide new knowledge to inform cost-efficient measurement, monitoring and verification (MMV) of the environment of CCS projects in coastal waters.

Kongsberg EM2040c Multibeam Echosounder – This multibeam echosounder is a bathymetric echosounder that has a frequency range of 200kHz- 400kHz. Two transducers were used mounted at 30° to increase across track coverage, commonly known as a dual head setup. The data was collected in dual swath mode to increase the alongtrack resolution.
